Subject: [PATCH] i2c-amd8111 bug fix (compare i2c-nforce2 bug fix)
Date: Thu, 19 May 2005 06:24:27 +0000 [thread overview]
Message-ID: <200311302339.11863.hfvogt@arcor.de> (raw)
Hi,
a similar bug for the send/receive byte SMBus transfer as in the i2c-nforce2
bus driver is also present in the i2c-amd8111 driver. The attached small
patch corrects it. I have no board with AMD-8111 and therefore cannot test
it, but the patch brings the AMD-8111 bus driver in line with the ACPI 2.0
spec chapter 13.9, to which is is compliant according to the AMD-8111 data
sheet (AMD document #24674). Can anybody with an AMD-8000 chip set based
mainboard confirm the fix?
Hans-Frieder
